H_4_01 — Propaganda, Information Control, and the Manufacture of Consent
The systematic manipulation of public belief is as old as civilization itself. Egyptian pharaohs chiseled out predecessors' names (damnatio memoriae), Roman emperors staged bread and circuses, and Chinese imperial histor
H_4_32 — Information Warfare, Propaganda & Manufactured Consent
Information warfare — the deliberate use of information and communication systems to gain strategic advantage — is as old as organized conflict, but the modern era has industrialized it. From Edward Bernays's founding of
